Mobile Hydro Rotor
The Mobile Hydro Rotor is a small hydro power plant designed to use river currents to generate electricity.
Mobile Hydro is creating an online Do-It-Yourself manual to allow use of different materials available locally. Additionally, Mobile Hydro is also developing an affordable pre-fabricated construction kit that includes important parts, such as tire tube, blade profiles, canvas cover and a generator.
Goal 7: Affordable and clean energy
Off-grid or under-supplied rural locations
This product is currently in the prototyping phase and not yet manufactured at scale.
Product is still in prototyping stage but users can contact Mobile Hydro for open source information to build a personal hydro turbine.

Whether the product is single or 3-phase
The Mobile Hydro Rotor is a modular kinetic hydro power plant designed to be low cost by allowing the use of recycled materials and standard components that can be built and assembled by the user. It is designed to be user friendly, with the system allowing for plug-and-play installation on site. It is a floating vertical axis pico turbine for economic performance at even low water flow velocities.
The H-Darrieus rotor used in this product has a diameter of 1.4 m and a height of 1 m.

Replacement components are available
The turbine is designed to provide 1 W of power at a river flow rate of 0.3 m/s, and up to 703 W at 2.5 m/s. The product is expected to produce 100-500 W on average.
Testing performed by Mobile Hydro at TUM Hydromechanics Lab
The turbine must not be placed in water bodies that people frequent.
An energy storage system could work in conjunction with the turbine.
